Abstract

Rock temperature is an important parameter in the process of predicting the maturity of hydrocarbons in sedimentary rocks and also can be used as the basis studies related to geothermal reservoir. Direct measurement in well drilling is to determine the temperature at determined depth. This measurement was not done thoroughly on the well, some have only do a measurements on the bottom of wells (BHT). This study estimates the temperature at each depth on well that surface temperature and Bore Hole Temperature (BHT) known using the development of earth heat flow basic concepts, by calculating thermal conductivity of group formation, temperature gradients of group formation and heat flow. These three parameters used as a basic to determine the change in depth on temperature rising at 10OC or 5OC. The temperature in each formation can be used as a parameter to calculate the amount of heat in the reservoir rock and the resulting temperature in each depth can be used as a parameter to estimate the hydrocarbon maturity. The thermal conductivity of rocks in this study obtained by measuring core in the laboratory and calculation based on rock porosity. These two method show a slight different price causing kF, kGF, gradT, kW, and heat flow have the same price of the rock thermal conductivity measurement and calculation. The temperature on the A1 well ranges from 27OC (surface) to 127OC (basement), while the B1 well ranges from 30OC (surface) to 100OC (basement)
